Dennis, That does not work. Next time when a new VM is created, it replaces the file with default host names. I think part of the challenge is Neutron does not know the host name associated with the port/vif, so it fabricates a hostname based on the IP address. DNS lookup works for the fabricated host name, but I need host entry with real host name.
Also this should be part of VM provisioning logic. I don't want to manually edit the host file.
